Thread: problems with structure

ur code is working fine but what is the problem is that i am not getting the exact readings. the last 240 is correct but the upper one is showing different readings. so I am checking it. U just be online please.

MK27..now the readings are fine but i used unsigned to display the minus sign too but while doing this i am getting different values after DewPointC. I got correct values for Time and DryPointC but for DewPointC i got all 0 and for RH i am getting some garbage values.

i didnot get u. So now how should i change the codes?

Code:

#include <stdio.h>
#include <string.h>

int main()
 {
	int Time, RH, retv;
	signed DewPointC;
	float DryTempC;
	char line[256];
	int i;
	FILE *in = fopen("KBIS_2005.txt", "r");
	for(i = 0; i<=240; i++) 
		{
			fgets(line,256,in);
			retv=sscanf(line,"%d %f %f %d",&Time,&DewPointC,&DryTempC,&RH);
			printf("%d items read: %d %f %f %d\n",retv,Time,DewPointC,DryTempC,RH);
		}

	return 0;
}

i used float too but while using it I am not getting the correct readings. Again I will try. I am using gcc compiler at linux.

Code:

#include <stdio.h>
#include <string.h>

int main()
 {
	int Time, RH, retv;
	float DewPointC;
	float DryTempC;
	char line[256];
	int i;
	FILE *in = fopen("KBIS_2005.txt", "r");
	for(i = 1; i<=241; i++) 
		{
			
			fgets(line,256,in);
			retv=sscanf(line,"%d %f %f %d",&Time,&DewPointC,&DryTempC,&RH);
			printf("%d items read: %d %f %f %d\n",retv,Time,DewPointC,DryTempC,RH);
		}

	return 0;
}
	

thnks now i am getting the correct readings. but i am getting wrong garbage values at the beginning. so how should i remove it.

yah i got it..but i am stil getting the garbage value at the beginning.how to delete those?

Code:

0 items read: 0 0.000000 0.000000 4196133
4 items read: 0 0.600000 -5.000000 67
4 items read: 1 0.000000 -3.900000 75
4 items read: 2 0.000000 -3.900000 75

i should not be getting the first values. I tried to change the values in the for loop but it is still reading that values.

Is there a "header" line at the top? (If so, you need to skip it.)
